What was Marty's condition + what happened to Tammy?
It says that Marty was paralyzed, it seemed from the waist down. However, was he born that way or was it an accident? The movie never really explains that part. I do think that Marty was catered to a little too much. I don't think the parents should feel guilty because it's not their fault their son had that condition. I understand why Jane gets upset sometimes when Marty gets more attention than her.
Also, I remember seeing Tammy with Marty in the beginning of the movie. After her Dad gets killed, you never see her for the rest of the flick, that's kind of strange. I'd like people's opinions on this, thanks.
